Rock climbing instructors, such as those here at the UAB rec center are qualified to help inspire you to move and strengthen your bodies in new and non-traditional ways. You will learn to push your comfort zone, while still maintaining your safety. With the help of belayers, climbers are safe to miss a foot hold, as they will remain suspended in midair like a spider.
Maybe you are afraid of heights... the way to deal with fear is to maintain steady, strong and deep breaths. You have to stop and focus on the reality that you are not going to die. You can then begin to explore the exhilaration of taking that chance to try and reach that next hold. With treadmill and weight lifting, exercisers may be able to function and perform on auto pilot, leaning and depending highly on muscle memory accrued through years of repeating the same movements over and over. Unlike these activities, when climbing, your brain is constantly involved and having to ready itself for new challenges.
